5 And complete the lab safety 50 mL distilled waterin a 150-mL about 4 g NaOH pelletson a balance. Add the NaOH pellets to the beakerone at a time. Mix with a stirring roduntil each NaOH pellet dissolves before addingthe next about 6 g Epsom salts (MgSO4)and place it in another 150-mL beaker. Add 50 mL distilled water to the Epsom salts. Mix with another stirring rod until theEpsom salts pour the Epsom salts solution into the NaOH solution. Record your the new solution. Record your the precipitate to settle, then decant the liquid from the solid into a 100-mL graduated of the solid as instructed by your balanced chemical equation for the reaction between the NaOH and sulfate compounds exist as ions in aqueous complete ionic equation for this ions are spectator ions, then write the net ionic equation for Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, and MiniLab WorksheetsChemistry.

7 By comparing how different metals react with the same ions in aqueous solutions,an activity series for the tested metals can be developed. The activityseries will reflect the relative reactivity of the tested metals.

Place a piece of Zn metal ineach row C well that contains the procedure in step 6 using 10 cm ofcopper wire. Place a piece of Cu wire in each row D well that contains what happens in each cell. After 5 minutes, record your observations in the data and of all chemicals and solutions as directedby your your equipment and return it to its your hands thoroughly before you leave (NO3)3Mg(NO3)2Zn(NO3)2Cu(NO3)2 AlMgZnCuReactions Between Solutions and MetalsAnalyze and and InferIn which wells of the reaction plate did chemical reactions occur?
